A rare solar eclipse will appear with Sunday’s sunrise, visible to residents in the United States’ Eastern Seaboard, parts of southern Europe, and anywhere in Africa.

The eclipse will be a hybrid, beginning as an annular one — meaning that the moon does not cover the entirety of the sun and leaves a fiery ring — before turning into a total eclipse.

Solar eclipses occur when the moon passes between the sun and the Earth, and when the moon looks almost the same size as the sun. The United States will only see a partial eclipse, while the moon will pass exactly between Earth and the sun over the Atlantic Ocean.
